1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Residue incorporation is a universally accepted agronomic practice around the world. However, the relationship between C and N turnover in soil is still not fully understood. We performed a soil microcosm incubation experiment to study the effects of residue incorporation with different C-to-N ratios (C/N) (low, 31.8; high, 84.5) on the SOC distribution, diazotrophic bacterial composition, and N accumulation in different particle size fractions (PSFs) of three types of soil parent material with different native C/N ratios. Our results demonstrate that SOC is 1.34 to 2.50 times more easily retained and accumulated in clay compared to baseline levels at the early stage of soil development. The native C/N ratio markedly affects the microbial metabolic characteristics and the SOC accumulation processes. Specifically, low C/N residue enhanced SOC accumulation in high-native-C/N soil, while the high-C/N residue maximized SOC in low-native-C/N soil. These shifts regulated the composition of the diazotrophic bacterial community, increasing the nitrogenase coding gene (
